When "N1>N2", the last detected event is associated with one optical splitter and indicated as "uncertain splitter" distinctly from normal splitters. Losses related to events at the "uncertain splitters" can be switched through user operation so as to be indicated as excluded from targets of determination. Events in a case where a level of back-scattered light cannot be determined due to the influence of a dead zone are also indicated as "uncertain splitter". Such events can also be excluded from the targets of determination.SELECTED DRAWING: Figure 3
